They all thought it was an epidemic call, Gu Yanan picked it up, but a familiar voice came, brother Gu Jiashu: "Little sister, our hospital has found several cases of tuberculosis in the past two days, and two of them have been reported to the epidemic system. ”

"Oh, tuberculosis is a chronic disease, this part is under the management of the slow communication department, after entering the information, the slow communication department will follow up on the Internet, and your hospital will treat the symptoms well."

"This is the procedure for dealing with ordinary TB cases, but we have found clusters."

"Huh? Clusters? Did you fill in the information online? I haven't seen any reports of the epidemic. ”

"I haven't had time to fill in the information on the epidemic system, I only did a chest X-ray for the patient, and found a typical lesion of tuberculosis, and I still need to do a few more diagnostic tests, there are a total of 5 girls, all of whom are staff of the Grand Theater Troupe, I suspect that there are other tuberculosis patients among the staff of their theater, as for how they were infected, this needs to be checked by your CDC."

"Okay, the patient's specimen will be sent to the Municipal Disease Control Laboratory first, and the culture of conjugated bacilli will be done, and I will take someone to the hospital immediately."

After hanging up the phone, everyone stared at Gu Yanan.

"There is an epidemic, a cluster of tuberculosis cases, and those who want to go to the scene follow me."

Lianhai First People's Hospital, Office of Infectious Diseasesman.

Gu Yanan, Lu Li, Wang Xiaoxiao, Xiao Chu, and three interns, a group of people poured into the doctor's office.

Gu Jiashu was surprised, "So many people? ”

"The emergency response team came with three interns to bring them to the scene."

"Oh, this is the dossier of all newly discovered tuberculosis patients at present, and no matter how specific the flow of the problem, you disease control people need to ask the patient." Gu Jiashu pushed a stack of medical records in front of Gu Yanan.

Gu Yanan and his entourage looked at the patient's information, and Gu Jiashu explained on the side, "In recent days, the infection department has received a number of tuberculosis patients, and all of them are initially positive. ”

Gu Yanan looked through the medical records, his hand suddenly stopped, took out one of them, and asked: "This person named Chen Yaozu is not an employee of the Grand Theater." ”

"Well, he is Chen Xiaohua, that is, the son of Chen's mother, is a tester, working in the laboratory department of Binhai District Hospital, although the chest X-ray is normal, but the PPD test is positive, he is an asymptomatic infection."

After reading the patient's information, Gu Yanan already had a flow idea and began to assign tasks to everyone.

Lu Li and Wang Xiaoxiao asked the patient about the basic flow of the patient through the ward telephone system according to the case flow table.

Xiao Chu went to inform Zhou Lao and Gao Fei to go to the Grand Theater to conduct a physical examination of the staff of the Grand Theater and screen out those infected with Mycobacterium tuberculosis.

The three interns acted separately, those who wanted to stay in the hospital to conduct a flow of patients followed Lu Li, and those who wanted to go to the Grand Theater to conduct physical examinations and screening of the staff followed Xiao Chu. ”

Intern Xiaojia: "Director Gu, what about you?" ”

"I went to investigate an asymptomatic infected person, Chen Yaozu."

"Why him? What's so special about him? I think as the director of the emergency office, I will definitely do the most important thing. Intern Xiao Jia asked to the end.

"Chen Yaozu is not a staff member of the Grand Theater, and his mother Chen's mother is a staff member of the Grand Theater, so there are two possibilities: the first possibility is that Chen's mother was infected by other people in the Grand Theater and then infected her son Chen Yaozu after returning home; The second possibility is that his son Chen Yao's ancestors were infected, and then passed the pathogen to Chen's mother, who in turn transmitted it to other people in the Grand Theater. If the latter is the case, then the source of the tuberculosis cluster has been found. ”

Intern Xiao Jia continued to ask, "Which one does Director Gu think is more likely?" ”

"It's all possible, if Chen's mother was infected first, then trace the source of infection from the Grand Theater, if Chen Yao's ancestor was infected, then his working environment and the surrounding people are the focus of the next investigation. But I'm more inclined to the latter possibility. ”

"Why?"

"Chen Yaozu is a hospital worker, and many of the confirmed tuberculosis cases in our city, especially the cases with cluster outbreaks, are iatrogenic infections."

"Do you suspect that Chen Yaozu was infected at work?"

"This is one of the possibilities, and it will only become clear after the on-site investigation."

"Oh, I'm going to go with Director Gu to investigate Chen Yaozu's scene."

——

Lianhai City, Binhai District Hospital.

Through investigation, Gu Yanan found that Chen Yaozu, who had been diagnosed with tuberculosis bacilli, was not isolated at home for treatment, but continued to work in the laboratory department of Binhai District Hospital.

Gu Yanan and intern Xiao Jia found the floor where the laboratory was located and found Chen Yaozu wearing a mask and busy inside.

Gu Yanan knocked on the door and showed his work card.

Although Chen Yaozu was wearing a mask, he couldn't hide the panic in his eyes.

"What are you CDC looking for me for?"

Gu Yanan glanced at the other busy people in the laboratory of the laboratory and said euphemistically: "Your mother is hospitalized in the People's Hospital, this time I came to discuss your mother's condition and the situation of the people around her, is it convenient to talk here?" ”

"Come with me downstairs in the garden."

Chen Yaozu greeted his colleagues and took Gu Yanan and intern Xiao Jia to the garden downstairs.

"What do you want to ask me?" Chen Yaozu lowered his head and tried his best to hide his panic.

Gu Yanan has rich experience in flow and is used to seeing all kinds of people, and there is a problem with the demeanor of this Chen Yaozu in front of him.

"We know that you are a carrier of tuberculosis bacilli, your mother has shown symptoms, and there is also a tuberculosis outbreak in the Grand Theater, your mother is an employee of the Grand Theater, I suspect that you and your mother are related to this tuberculosis outbreak, so come and investigate."

"Tuberculosis outbreak in the Grand Theater?" Chen Yaozu's eyes flashed with panic, disbelief, and hesitation, and finally he wanted to speak and stopped.

Seeing this, Gu Yanan continued: "There are a lot of iatrogenic cases of tuberculosis in our city, because you work in a hospital, there is a possibility of being infected, and your colleagues around you are also likely to be infected, so our disease control and control will also conduct a tuberculosis screening of your colleagues around you, and patients who have recently come to your hospital will also be investigated." You know, we have a big epidemic system for disease control and control, and we know all the information about tuberculosis patients who have been here for examination, who has tuberculosis. ”

Chen Yaozu was completely panicked, he originally wanted to hide his previous experimental mistakes, but after hearing the disease control staff say this, patients can follow the traces when they come to the doctor, and they will find out very clearly when the time comes.
